Throttle Body Temperature Sensor

Print

The throttle body temperature sensor is a device which monitors temperature of the throttle body. This is useful as the reading is normally very close to the fuel temperature. The sensor is mounted in the throttle body. Information provided by the sensor helps allow the SMEC to provide the correct air/fuel mixture for a hot restart condition.
